1. TECHNICAL DESCRIPTION

1.1. Radial drilling machines can be used for drilling, boring, reaming and taping.

1.2.The arrangement of the machines is traditional for radial drilling machines and includes:

The stationary base plate with T-slots for clamping the work pieces, fixed on foundation, on which either socle (2A554; 2A554-1) or stationary inner pillar (OC2146; OC2567; 2A576 and 2A587) is mounted.

The pillar, rotating round the vertical axis together with the sleeve, by means of socle bearings (2A554; 2A554-1; 2A554-2), or the outer pillar, rotating by means of bearings round the inner pillar (OC2146; OC2567; 2A576 and 2A587).

The sleeve provided with possibility of vertical travel along the outer pillar and rotation round the vertical axis together with it.

Drilling head, provided with possibility of horizontal travel along the sleeve guides

Spindle, mounted in cylindrical quill, provided with possibility of vertical travel in the drilling heads housing.

1.3. Feed is provided by spindle quill. All the rest travels are positioning.

1.4. All the displaceable parts of the machines are moving with minimized efforts and are fixed in operating position by means of hydraulic clamping devices.

1.5. All the control devices are concentrated in the control panel of the drill head.
